Manually fix a few tables in advance of clang-format.

clang-format gets very confused by the comments in these tables. (The
comments seem to have already gotten a little messed up from upstream's
reformatted.) Reformat them ahead of time. I removed the tag2str number
comments as they aren't really doing much good at this point.

Also remove the last entry in tag2bits because it's not actually used.
ASN1_tag2bit only reads the first 31 entries.
